CONTROLLED-DISCHARGE DUMP CAR.

Application filed July 26,

This invention relates to dump cars of the kind in which the cargo, when discharged, is deposited in definite relation to thetrack or right of way, for instance, wlthin more or less defined limits between the rails and on either side thereof.

The object of the invention is to provide means through which to effect a more exact control of the discharge and a better defined limitation in directions transverse to the right of way, of the piles of material (leposited, thcreby avoiding waste of material which might otherwise pass beyond the area requiring the material, or unnecessary labor in bringing the material back to where it is needed.

It has heretofore been proposed to provide a hopper bottom dump car with a door or doors indpendently controllable, adapted to assume positions from which, when the doors are open, they will direct the material to eit er the space between the rails of a railway track, or the outer sides of the rails; but in dump cars of this kind as heretofore constructed, owing to the force with which the material issues over the opened door or doors, and particularly between the time of initial opening and the time the door reaches full open position, during which its angle of elevation is too great to properly direct the material, a considerable portion of the cargo is deposited too far from the point desired. The present invention avoids this objection by providing, at the discharge opening, and in cooperative relationship to the door, a bathing apron which restricts flow of material over the door at the time of discharge by assuming a position-at a substantial angle to the dii'ection of flow, and at a distance from the door which will enable it to reduce the vertical dimension of the stream of material; such bafiling a ron or bafile being movably mounted, as, or instance, by hinging it upon an axis parallel with that upon which the door swin s, and has its axis of move to that of the door that commencing with the beginning of opening movement of the door and continuing until such time as the door shall have reached a predetermined angle of elevation at which it exercises proper control over the material, the baflle will meet and remain in a relation of meeting or approximate meeting with the door, thereby preventing escape of material 1926.- Serial No. 124,966.

so long as the door is at an angle which is undesirable for directing the material, and preferably when the door has reached full opening )osition, will still remain as a controlling actor in the discharge by regulating the vertical dimension of the stream of material by the distance of the bafile from the door.

In accordance with subordinate features of the invention incident to the broad principles above outlined, the batilin apron or battle has its axis of pivotal action located in or at such proximity to the plane of the door when closed that it will overlie the door, so that it will have the advantage of being sustainedby the door elevating and securing means, through the medium of the door upon which the swinging end of the bathe rests, as well as the advantage of remaining in supported relation to the door, in resisting escape of the cargo throughout the fore part of the doors opening -movement.

The invention applies to doors opening toward the middle of the track as well as those opening toward the sides.

The accompanying drawing, in which the invention is illustrated more or less schematically, represents a vertical transverse section through the lower rtion of a known design of selective 'ump car for transportation of subdivided material in bulk, and shows the preferred embodiment of the invention incorporated therein by way of illustration.

1 represents the center sill of a car, 2 the side walls-of the hop or bottom thereof, and 3 and 4 are, respectlvely, side and middle discharge doors pivotally mounted upon a common horizontal axis 5 extending longitudinally of the car and adapted to assume either the closed positions illustrated at the right side of the figure, to which they may be moved by any approved form of closing means, such, for instance, as flexible connections 6, 7, leading from manually or otherwise controlled winding drums 8, 9, over pulleys 10, 11 to the side doors 3 and 4, or adapted to assume, under the force of gravity, the open positions shown at the lefthand side of the figure, when their elevating connections and any looking or securing means with which they may be provided are released. Mounted upon fixed ortions of the ear structure, for instance, t rough the medium of hinges 12 and 13, adjacent the swinging ends of the doors when in closed position, are bafiles 14 and 15 in the form of aprons which, when the doors are closed, overlie and have their free ends supported by the doors, as shown at the right-hand side of the figure, but which, when the doors are opened, drop to substantially vertical or other predetermined position, as shown at the left-hand side of the figure, and in which latter position the battles are adapted to materially restrict and retard the flow of material from the car and prevent it cascading to a point beyond the area in which it is needed. More than this, the battles 14 and 15, by means of the relation of their free ends to the doors through a large part of the arc of opening movement of the doors, during which their said free ends are in meeting or substantial meeting with the surfaces of the doors, will delay the time at which. discharge commences, until the directing angle of the door is approximately that selected to effect the form of delivery desired. In other words, one important. feature of the bailie control is that resulting from its influence over the stream of material after the door reaches its predetermined inclination'of full open position. Another lll'lPOI'tzUll; feature is that which arises from obstruction of cargo during the fore part of the opening movement of the door.

While the invention has been described in connection with both of two different doors discharging, respectively, inwardly and out wardly relatively to the track, and the doors selected for illustration are mounted upon axes extending longitudinally of the'car, the invention is applicable to single doors in various positions; nor is it limited to the specific relation of the baiile to the door, or the particular construction of battle shown.

Any suitable means may be employed for swinging the baffles 14 and 15 toward closing position sufficiently in advance of the upward swinging of the doors 3 and 4, or until the battles are at such angles as will enable the doors to assume control of their closing movements. For instance, the flex- 'ible connectors 6 and 7 may be passed from the guide sheaves or pulleys l0 and 11, not directly to the doors 3 and 4, but indirectly by way of guide sheaves or other deflecting surfaces 16 and 17 mounted at the sides of the bafiies at points which, when the doors and bafllesare in closed position, will substantially coincide with the points 18, 19 at which the flexible connectors meet the doors, the effect being to permit the parts to assume positions shown at the left-hand side of the figure when the elevating means are fully released, but by the tendency of the connectors to conform to a straight line under tension when wound upon drums 8 and 9, first to draw the bafiles 14 inward to a point where they will readily deflect upward under pressure of the door (which point can readily be gauged by the ofl'set of the guide points 16 and 17 from the planes of the battles) and thereafter be moved to fully closed position in which they overlie the doors, as at the right-hand side of the figure, under the full closing movement of the doors. 7
